At the top of "Rocce Rosse" you'll have an amazing view: the southern part of Lago di Lugano is visible with Porto Ceresio. You can also have a picnic on the top of the rocks.

The area is very interesting from a natural point of view due to the abundance of springs and the presence of travertine, a sedimentary rock with a porous appearance. In addition to the main waterfall, other waterfalls can be admired from the terraces and along the well-equipped paths that start behind the square. A series of information panels clarify some details. The Valganna Caves are a place very well known by the inhabitants of Varese: we are in fact on the outskirts of the capital, literally a stone's throw from the road that leads to Valganna. (Info from the internet 😉)
